|Anime Debut||Episode 01|
Ryouko is the commander of the AST, a team of Japanese <Wizards> with the mission of killing the Spirits. Despite this, however, she is more concerned with the safety of her teammates than actually fulfilling her duty. She therefore often butts heads with Origami due to her often endangering herself in her pursuit killing the Spirits.
While Ryouko, along with the rest of the AST, started out as an antagonist, she became regulated to a minor character role after DEM took the role of the series' main antagonists. She eventually joined Ratatoskr and aided help them in fighting DEM due to a difference in ideologies.
Ryouko is a young woman in her mid-20s. She has long, glossy black hair which is tied into a ponytail with some bangs left out into three separate parts. She also has a pair of black eyes.
She is often seen wearing her dark cyan military uniform with a hat on top of her head whenever she is at the JGSDF base and wears the AST's wiring suit during combat. In Rinne Utopia, Ryouko wears a red T-shirt underneath a white, long-sleeved shirt with unfastened collar.
Ryouko, for the most part, is often childish and gets angry when annoyed. Despite this, she is dedicated to her position and prioritizes civilian safety during spacequake attacks, and was outraged by DEM Wizards not following these same beliefs.
Ryouko first joined the AST when Kyouhei Kannazuki was still commander of the team. While disturbed by the unusual punishments he used to keep her and her fellow <Wizards> in line, she respected him due to his skills with the <Realizer>. After Kyouhei left the AST, Ryouko succeeded him as commander of the team.
Over the years, Ryouko seems to have given up on killing the Spirits. Instead, she became more concerned with the safety of her teammates while being content with just minimizing the damage the Spirits caused. Because of this, she often butted heads with her teammate Origami, who would often recklessly put herself in danger to attempt to kill the Spirits. Despite this, however, Ryouko still saw Origami as a friend.
